Convert object to String using Iterator pattern
When manipulating JSOM, XML, Java beans and other objects, you may first think of the visitor pattern. But using the visitor pattern it is difficult to control callbacks from the calling code. For example, you cannot conditionally skip a branch from all callback sub-branches and leaf nodes. To solve this problem, you can use the Iterator pattern to traverse the entire object and generate a string that is easy for developers to read and debug. This iterator is quite versatile and I've used it in both tools for finding Java objects using XPath and logging exceptions in StackHunter.
